Patented July 27, 1937 STATES PATENT OFFICE WINDOW REGULATOR Albert W.Susor, Toledo, Ohio Application August 10, 1936, Serial No. 95,151 1claim. (o1. 74 421 This application relates to window regulators andmore particularly to regulators for automobile door windows.

A principal object is to provide a regulator which is so designed thatit can be mounted on right or left hand doors of an automobile, asdesired; this eliminates the present necessity of designing,manufacturing, and stocking separate parts for right hand doors and forleft hand doors, with the attendant difiiculty of keeping these separateparts in separate stocks.

A further object is a regulator having a novel gear guard forrestraining axial shifting of regulator gears with a minimum of frictionbetween the gear guard and the gears.

A further object is a regulator whose mounting plate is so designed thatit can be made from strap stock of uniform width and whose ends arecomplementary in shape, though irregular of outline, so that waste ofstock and a multiplicity of end shaping operations are eliminated.

The regulator hereof is shown in the appended drawings. In thesedrawings,

Fig. 1 shows an automobile door having a surface thereof cut out toexpose the regulator;

Fig. 2 shows the regulator per se;

Fig. 3 is an obverse view of Fig. 2;

Figs. l, 5, and 6 are sections on lines 4-4, 5-5, and Ei-'5 of Fig. 3.

Fig. 1 shows a door ill between whose surfaces H and i2 is disposed aregulator for raising and lowering the window it. The regulator includesa mounting plate 28 having a pinion ill thereon adapted to be operatedby the exposed handle 22 and provided with a stub shaft 23 adapted to bereceived within the socket of a socketed portion 2'3 of the handle 22,the stub shaft projecting through a hole in the surface l 8. Within thedoor is a frame part (not shown) to which the mounting plate is securedby means of bolts or screws (not shown) threaded into nuts 25permanently secured to the mounting plate at the corners thereof.

In order to insure the regulator here shown being useful on right handdoors as well as on left hand doors, and vice versa, the nuts 25 on0pposite ends of the mounting plate are so positioned that the pinion 23is centered exactly between them. As indicated, the distances a-a areidentical and the distances b-b are identical. While in the embodimentillustrated the distances a-a are identical with the distances bb, thisis merely a happenstance and not a necessity.

J ournalled on bearings 27 of the mounting plate are gears 28 to whichare fixed window regulator arms 2@ and on which are counterbalancesprings (not shown). To restrain axial shifting of the gears 28, thereis provided a gear guard in the form of a lug 3| having a. portion 32contiguous to and riveted to the mounting plate 20 and a portion 33spaced from the mounting plate and between which and the mounting plateare the gears 28; the corners of the portion 33 are bent down asindicated at 34 towards the mounting plate 20 to engage the gears 28 andthus restrain axial shifting thereof, and, because the corners 34 areminute and engage the gears in what amounts to substantially a pointcontact, the

friction on the gears as they rotate, created by the engagement thereofby the corners 34, is a minimum.

The mounting plate 20 is to be made from strap stock and therefore is sodesigned that its transverse cross sectional area is substantiallyuniform whether the cross section be through the deformed corners ii! ofthe mounting plate in which are seated the nuts 25, or through thestrengthening rib M of the mounting plate, or through any other part ofthe mounting plate. Though the shape of the cross section varies fromend to end of the plate, the area of the cross section is uniform. V

In order to provide a bearing for one of. the gears 28, withoutincreasing the length of the mounting plate as a whole, the centralportion of the end of the mounting plate on which that gear 28 isdisposed is extended longitudinally from the termini of its longitudinaledges, resulting in an irregular contour for such end of the mountingplate, which contour is illustrated by the line 42. The other end of themounting plate is contoured complementary to the contour represented bythe line 4 2, as indicated by the line 43, and therefore the mountingplate may be cut from strap stock in a single out which shapes theextended end of one mounting plate and the inset end of the nextadjacent mounting plate, and by a single cut adjacent edges of twomounting plates are cut without waste.

Now having described the regulator herein shown,.reference is had to theclaim which follows for a determination of the protection sought herein.

I claim:

In a window regulator, a mounting plate, meshing gears thereon, and agear guard therefor, the latter comprising a lug separate andindependent of the mounting plate but permanently fastened thereto andhaving a portion contiguous to the mounting plate and a portion spacedfrom the mounting plate and between which and the mounting plate are thegears, minute parts of the last mentioned portion being bent inwardlytowards the gears and engaging them with substantially a point contactto restrain axial shifting thereof.

ALBERT W. SUSQR.
